Hi, Kasirye! 18.000 Btu A/C in most cases used 35 or 40 mfd cap. , during start up if the capacitor is too short it may hang and the compressor can heat up. But if you h've an amp. meter you can also measure the current of the compressor if it is in the range given on the name plate on the outdoor unit. Also you may check the charge of freon (example. 22) in the system. the suction has to be between 60-70 and the suction 225-275 psi (normal weather). If ihere is an over charge, you can have compressor overheating too!! I hope this was helpful to you!!

Hi, hild, first thing; stop the AC by remote controler, than select the fan option pressing by mode button and next start the AC, wait 8 minutes, if the unit still blows cold air, the thermistor has to be replaced. I hope this was helpful to you! success!
